Bill Currie 5477352e93 [renderer] Abandon sw32 altogether
I'd been considering it for a while, but in the end, all the issues it
presented made me decide it wasn't worth merging and was never really
worth keeping: it was a neat proof of concept but of little actual use,
especially now everyone either has an OK GPU or would want to stick to
8-bit rendering anyway (sorry L-Havoc).

However, both it and my merge work are preserved in git history :)
